Phenolndi mankhwala ofunikira mafakitale omwe amagwiritsidwa ntchito pamapulogalamu osiyanasiyana, kuphatikizapo kupanga pulasitiki, wotsetsereka, ndi mankhwala. Phanol yapadziko lonse ya Phenol ndiyofunika, koma funso limafunikanso: Kodi gwero lalikulu la zinthu zofunika izi ndi chiyani?

Kuchulukitsa kwakukulu kwadzikoli kwa phenol kumachokera ku magwero awiri akuluakulu: malasha ndi mpweya wachilengedwe. Tekinoloje-mankhwala, makamaka, yasintha kupanga phenol ndi mankhwala ena, kupereka njira yokwanira komanso yotsika mtengo yosinthira malasha mu mankhwala ofunikira kwambiri. Mwachitsanzo, ku China kwaukadaulo wamoto ndi njira yabwino yopangira phenol, yokhala ndi mbewu zomwe zimakhala mdziko lonse.

Gwero lachiwiri la phenol ndi mpweya wachilengedwe. Mafuta achilengedwe a gasi, monga Methane ndi Ethane, amatha kusinthidwa kukhala phenol kudzera mwa mitundu ingapo yamankhwala. Njirayi ndi yolimba kwambiri koma imapangitsa phenol yapamwamba kwambiri yomwe imathandiza kwambiri kupanga mapulagisi ndi zotupa. United States ndi wopanga zinthu zachilengedwe zochokera ku phenol yochokera m'masitolo, yokhala ndi malo omwe ali mdziko lonselo.

Kufunikira kwa phenol kukuchulukirachulukira padziko lonse lapansi, kumayendetsedwa ndi zinthu monga kukula kwa kuchuluka kwa chiwerengero cha anthu, kufalikira, ndi kupota mimba. Izi zikufunika kukulirabe m'zaka zikubwerazi, zomwe zikusonyeza kuti ntchito yapadziko lonse lapansi yopanga zotsatirazi idzachitika ndi 2025. Mwakutero, ndikofunikira kuganizira njira zokhazikika popanga izi mankhwala ofunikira.

Pomaliza, ambiri mwa mitundu ya dziko lapansi imachokera ku magwero awiri akuluakulu: malasha ndi mpweya wachilengedwe. Ngakhale magwero onse ali ndi maubwino awo opindulitsa komanso zovuta zomwe zimapangitsa kuti achite zachuma padziko lonse lapansi, makamaka popanga mapuloma apadziko lonse lapansi, zotsekemera, ndi mankhwala. Kufunikira kwa phenol kukupitilizabe kukwera padziko lonse lapansi, ndikofunikira kuganizira njira zofunika kwambiri zopangira zofunikira zachuma ndi zovuta zachilengedwe.
